Application filed. 1i tilcll 1, 1910. Serial no. 546,722. r

lie it known that I, Jenn B. llannr, a. citizen of the lnitcd vt'Statee, residingat Even, in the county oil ll'alton and State of Florida, have .inveutml new and useful lire uovenrents in ifvaporating-Pans, of which the 'lollowing is a spe ification.

This invention relates toan evaporating pan, for i'nalqing rups, jellies, preserves, etc., the object of the invention being to provide a simple, iru. pei1siv and efficient construction of evaporating pan emborily ing means for heating the pan by the action the boiling of the juice and its separation from the impurities whereby the latter may be removedin an expeditious manner and with a minimum amount of trouble and labor. 1. r

Theinrention consists in the novel construction, combination and arrangement of devices, hereinafter fully described, illustrated and claimed.

In the accompanying drawing: lg-arc 1 is a top plan View ofan evaporating pan embodying my invention. Fig. 2 is a vertical, transverse section of the same. Fig. 3 is :1. Vertical, longitudinal section on the pan. Fig. 4 is a horizontal section taken on the plane indicated by the line 4l-i of Fig. 3.

l'teferring to the drawings, 1 designates the body of the pan, which is of oblong form and may be of any suitable length and width, and is supported in practice in an inclined position for the flow of the juice by gravity from the inlet to the discharge, end.

The pan is made in practice of sheet metal and providedwith a bottom 2, above which is arranged a. false bottom or horizontal partition 3, extending the full length and width of the pan. This false bottom or partition 2") separator the body 01 the pan to term a lower heating chamber or compartment t and an upper boiling or ewnmratiug coinpartment 5, which latter may he oi a. desired depth to hold a. considerable (pinotity oi juice.

[The com mrtment 3 is providw transversely extending vertical pnriii and 7. i'nrojeeting alternately in opp-o4: rections from the side wallw oi the pan and i tei urinating short oi the opposite side wal I thereo'l thus tor-mine af zip-21c; or ii'ruilour passage For the flow of the j ce iron: th up per transverse portion 8 o t the pas age. forming the inlet; end thercol, to a lower transversebranch i) of the. passage, forming the discharge end thereof, at which point the pan is provided at one' side with a valved outlet-it) for the passage of the syrup. The raw juice may be ied into the branch 8 in any preferred manner, and flows by gravity tl'ierctroin back aud'forth through the compartnient 5 in which it is heated and clariiictl until it reaches the branch 9 in the form ct pure syrup, and then passes through the outlet" l0 into any suitable receptacle. 'lhe. heating compartment 4- also provided with verticnl transverse partitions lland 12,1! tending; alternately from opposite sides thereolwuu'l also the full distance between the bottom wall 2 and superposed false bot} tom which'thev are riveted or otherwise suitably fast'enel, The tree end o'f' each partition 11 and 12 terminates short o'lfthc side wall op 'iosite'that from which itox; H tends to provide a zigzag or circuitous steam channel or passage 13 leading from one side of the. lower end oi the. pan to the opposite side of the uppereud of the pan. As shown, the lower end of the pan is provided atone. side with a valved steam inlet ll, while the upper end of the pan isprovided at. its opposite side with a valved. steam exhaust. con-.

nection or outlet 1:), whereby the steam on its passage through the zigzag channel will heat the false bottom 3 and. the contentsot the chamber 5 and linally exhaust throl'igh the outlet 13. By the provision ot a cluinne'l ol' the t'orin described, all of the available heat. units of the iiowiu; steam are utilized, and the construction oi. the pan, as a whole, is also o'l such a simple character as to enable it to be conveniently niannihclured at a low cost.

I l tywii a: observed that the partitionsv t) and T consist of angle meta plates, each having an end llang'c (5 secured to the sidewall oi the cvn p i-rating compartinent l'roni which it extend; by rivets (3" and a base tiange (3 which br-nrs against the partition 3. Aleo that the partitions 1'1 and .12 within the landing: rznnparimenls are of channelet'l slu p-ta. each having upper and lower horizon! al l zm 'is or webs '19 and 12?. said webs l? bein; .'--i-cur d to the bottom wall 2 by rivets 12", while the webs ll bear against.

. the under side. oi the partition 12 and are united thereto by rivets 12. Certain of the partitions Hllilttlltlil with the partitions (3 and 7 and a re united therewith to the partition by the l l and it) are arranged in vertical rivets 12, which pass through the base flanges of the transverse partitions in the evaporating compartment and through the upper flanges of the underlying partitions in the heating compartment, By this construction an exceedingly strong and durable evaporator is provided and the partitions secured firmly against possible loosening or displacement;

In the operation of the pan, thevalves in the connections 1i and 15 are opened allowing steam to pass into and flow through the channel 13, until the wall 3. is heated to the desired degree, when the raw syrup to he treated is allowed to flow into the inletend S of the zigzag syrup channel in the compartment 5. This syrup on its flow throughthe channel will be heated to the boiling point, whereby the scum and other impurities will be caused to rise therefrom, thus clarifying and otherwise purifying the juice, which, when it reaches the lower end or branch of the channel, is ready for discharge through the outlet 10 and storage into 1eccptacles.foicommercial use.

It will be understood that by causing the steam to flow in an upward direction through the heating chamber, or in a direction reverse to the flow of the juice through the channel in the evaporating chamber, the juice in the lower branchesof the channel 13 will be heated progressively to a much higher degree than the juice in the upper branches of the channel, in Which latter, the juice will be comparatively coo]. By this method of treatment, the juice will be boiled and claris iied to a high degree before it reaches the lower branches of the channelwhile at the same time the scum and other impurities rising from the lower portion of the body of the juice will be caused to flow back on the comparatively still or calm cooler portion of the body of the juice, from which it may be easily and conveniently skimmed or other-wise removed. As a result, the hot juice at the lower end of the passage will be clear and free from scum and will discharge through the outlet 10 without'dra'wing any of the scum or-- other impurities with it, whereby an absolutely pure and clear syrup will be obtained in a simple and convenient manner and with a minimum amount of trouble and labor.

Having thus described the invention, what is claimed, is

An evaporating pan comprising an oblong rectangular body having a bottom, a horizontal partition above the bottom and dividing the pan to provide an upper evaporating compartment and a lower heating compartment, transverse partitions extending alternately-froin opposite sides of the evaporating con'ipartment and forming azigzag syrup channel, each of said partitions having an endflange to bear against and riveted to the side wall from which it extends and a. base flange resting on the horizontal partition, channeled transverse partitions extending alternately from opposite sides of the heating. compartment and each having a base flange riveted to the bottom of the evaporator body and a top-flange riveted to the horizontal partition, certain ofsaid transverse partitions in the heating compartment being arranged in alinement With the transverse partitions in the evaporating compartment, rivets passing through the horizontal partition and the upper heating and evaporating compartments, valved inlet and.outlet passages communicating with the ends of the syrup channel, and valved inlets and outlets connected with the ends of the heating channel.

' In testimony whereof I atfix my in presence of two Witnesses.
